the turn signal slightly sticks away from the back of the cover, and I kind of like the fact I can see the little halo of it being on, at night people behind me can see it too, so it's just an extra indication I am making a turn, and no it's not distracting at all, the angle it is in, while seated inside the car doesn't create a weird reflection or annoyance. In the daylight you can't see it.

but if it does, you can use a black silicone from inside the cover around the turn signal to seal any light leak into the mirror housing.
